Metal–organic framework (MOF) NH 2 ‐Uio‐66(Zr) exhibits photocatalytic activity for CO 2 reduction in the presence of triethanolamine as sacrificial agent under visible‐light irradiation. Photoinduced electron transfer from the excited 2‐aminoterephthalate (ATA) to Zr oxo clusters in NH 2 ‐Uio‐66(Zr) was for the first time revealed by photoluminescence studies. Generation of Zr III and its involvement in photocatalytic CO 2 reduction was confirmed by ESR analysis. Moreover, NH 2 ‐Uio‐66(Zr) with mixed ATA and 2,5‐diaminoterephthalate (DTA) ligands was prepared and shown to exhibit higher performance for photocatalytic CO 2 reduction due to its enhanced light adsorption and increased adsorption of CO 2 . This study provides a better understanding of photocatalytic CO 2 reduction over MOF‐based photocatalysts and also demonstrates the great potential of using MOFs as highly stable, molecularly tunable, and recyclable photocatalysts in CO 2 reduction.
